Useful before impressive
The work must change a real decision, behaviour or outcome.
About
Small enough to stay close.
Built to create options.
Convexify is a boutique AI firm based in Andorra. We work with organisations that face problems too specific for generic tools and too important to hand to a large vendor: the knowledge that lives in a few people’s heads, the decision that has to be made a thousand times a day, the product that only makes sense if it is built around how the business actually works.
The boutique advantage
Less distance between the problem and the people solving it.
The people in the first conversation are the people shaping the thesis, testing the experience and reviewing the result. That continuity preserves context and makes it easier to notice when the problem has changed.
We use agents to increase our range, not to hide junior work behind senior names. Taste, accountability and the final judgement stay human.
What never changes
A clear human bar for every intelligent system.
Evidence before scale
Autonomy expands only after a system earns trust on representative work.
Ownership before lock-in
Knowledge, documentation and operating capability remain with your team.
Identity before efficiency
Faster is not better if it makes the experience generic.
The people accountable
One founder at the front. Senior collaborators where they change the outcome.
Founder
Javier Sáez Hurtado
Leads strategy, architecture and delivery at Convexify. Also Head of AI Heroes at Learning Heroes. Builds multi-agent systems, knowledge systems and AI products, and transfers the capability to the client’s team.
Convexify is deliberately small. The founder leads every engagement and brings in specialised collaborators (engineering, design, evaluation, creative) only where they change the outcome. Nobody is hidden behind a bigger org chart, and the people you meet are the people who do the work.
Partnerships
An OpenAI Select Partner.
Convexify is an OpenAI Select Partner in the OpenAI Partner Network since September 2026. The status brings early access to OpenAI models and products, enablement for the team and direct support when a system moves from prototype into production.
It does not decide the architecture: we still choose the model that fits each problem, and the client keeps the code either way. What it changes is how close we are to the frontier we build on.
About the partnership Where we are
Andorra. Europe. Everywhere.
Convexify SLU is registered in the Principality of Andorra and works with organisations across Europe, on site and remotely.
Questions about Convexify
- What is Convexify?
- Convexify is a boutique AI firm registered in the Principality of Andorra and founded in 2025 by Javier Sáez Hurtado. It designs AI strategy and builds intelligent products and AI agents for organisations with complex, high-context problems, and transfers the capability to the client's own team.
- What does the word convexify mean?
- To convexify is to turn complexity, volatility and new intelligence into an advantage that compounds: not to predict every future, but to make a business ready for more of them. The name comes from convexity, where the upside of being right outweighs the cost of being wrong.
- What does Convexify do?
- Four things: AI strategy (where AI creates a durable advantage and what not to build), intelligent products (bespoke software with intelligence at its core), AI agents (autonomous systems that carry context and use tools under human control) and talks and workshops for leadership teams and builders.
- How does Convexify work with clients?
- In small senior teams with short learning loops. Every engagement starts with the hard problem, not a service line, and ends with owned code, documentation and a team that can keep building. Autonomy in any system expands only with evidence from real work.
- Is Convexify an OpenAI partner?
- Yes. Convexify is an OpenAI Select Partner in the OpenAI Partner Network (since September 2026). The status brings enablement, early access and support for deployments on OpenAI models. Convexify remains independent and chooses the model that fits each problem.
- Where is Convexify based and where does it work?
- Convexify is registered in Escaldes-Engordany, Andorra, and works with organisations across Europe, on site and remotely. Contact: hello@convexify.tech.
